Definitions

  • the subject matter disclosed herein relates generally to surgical devices as well as to surgical techniques for electrothermal hemostasis.
  • Electrosurgical techniques can be useful to achieve coagulation of fluids on lacerated tissue or like bleeding lesions.
  • argon beam coagulation (ABC) techniques argon gas is directed onto the target tissue.
  • the ABC technique also introduces electrical energy (e.g., current) at radio frequency (RF) into the argon gas.
  • RF radio frequency
  • the ABC technique has been more successful than other surgical techniques in achieving hemostasis in solid organ injury, like splenic injuries for example, and is especially valuable in treating patients with blood coagulation deficiencies.
  • the ABC technique has been shown to result in reduced operative blood loss, recurrent bleeding, surgical time, and surgical plume.
  • Conventional ABC surgical devices emit an argon gas jet with specific permanent features, such as area, diameter, cross-sectional area, and like geometries.
  • argon gas jet if a feature of the argon gas jet is too large for the target tissue area, there is a potential of damage to healthy tissue and floating eschar.
  • an argon gas jet that is too small for the target tissue area can require increased surgical time, which may lead to increased operative blood loss.
  • a surgical apparatus configured to allow an end user (e.g., a surgeon) to change the affected area of the target tissue during ABC techniques to lessen the risk of tissue damage while still achieving the aforementioned benefits of the ABC techniques.
  • Embodiments of the present invention recognize that there are potential problems and/or disadvantages with the conventional devices for argon beam coagulation techniques as described above. Therefore, a need exists for a surgical apparatus configured to allow an end user (e.g., a surgeon) to change the affected area of the target tissue during ABC techniques.
  • the embodiments can be used in surgeries e.g., orthopedic surgeries, gastrointestinal surgeries, particularly those involving the liver, and neurological surgeries, that might benefit from capabilities to coagulate both large and small areas quickly on a single device. These capabilities can reduce surgical time and blood loss, as well as to avoid introducing additional equipment into the surgical procedure.
  • Various embodiments of the present invention may be advantageous in that they may solve or reduce one or more of the potential problems and/or disadvantages discussed herein.
  • the present disclosure is directed to an inventive configuration, structure, and resulting function of a surgical apparatus configured to adjust the affected area of the target tissue during ABC techniques.
